Abstract

Methods, devices, and systems for beam processing of plate-shaped or tubular workpieces are provided. In one aspect, a method includes: generating at least one section of a cutting gap cutting through the workpiece along a cutting line corresponding to at least part of a contour of a workpiece part to be produced from the workpiece by a processing beam, and performing at least one non-joining and non-cutting finishing treatment of the workpiece with a partially cut-out workpiece part at least in one section of at least one finishing zone by the processing beam, the finishing zone extending along the cutting line.

What is claimed is: 
     
         1 . A method for beam processing of a plate-shaped or tubular workpiece, comprising:

         2 . The method of  claim 1 , wherein the finishing treatment of the workpiece is performed between generation of two sections of the cutting gap. 
     
     
         3 . The method of  claim 1 , wherein the finishing treatment of the workpiece is performed in a section of the at least one finishing zone extending at least partly along a section of the cutting gap. 
     
     
         4 . The method of  claim 1 , wherein the finishing treatment of the workpiece is performed in a section of the at least one finishing zone that at least partially does not include a section of the cutting gap. 
     
     
         5 . The method of  claim 4 , wherein the finishing treatment of the workpiece is performed continuously in the section of the at least one finishing zone that extends along the section of the cutting gap. 
     
     
         6 . The method of  claim 1 , wherein sections of the cutting gap successively extend the cutting gap. 
     
     
         7 . The method of  claim 1 , wherein a last-generated section of the cutting gap has a length that is shorter than respective lengths of previously generated sections of the cutting gap. 
     
     
         8 . The method of  claim 7 , wherein the lengths of the sections of the cutting gap, starting from a free-cutting point of the workpiece part, are kept constant or increase counter to a direction for generating the cutting gap. 
     
     
         9 . The method of  claim 1 , wherein, during a finishing treatment of the workpiece, at least one of a workpiece part-side cutting edge of the cutting gap or a residual grid-side cutting edge of the cutting gap is included in the at least one section of the at least one finishing zone. 
     
     
         10 . The method of  claim 1 , comprising:
 prior to a finishing treatment of the workpiece in a section of the at least one finishing zone, applying a layer of an anti-adhesive agent to the workpiece at least in the finishing zone, the anti-adhesive agent being configured to inhibit adhesion of substances produced during the finishing treatment.   
     
     
         11 . The method of  claim 1 , wherein the processing beam is guided with a meandering movement along at least one section of the cutting line during performing the at least one non-joining and non-cutting finishing treatment of the workpiece. 
     
     
         12 . The method of  claim 1 , comprising:
 cutting free the workpiece by the processing beam after performing one or more finishing treatments of the workpiece.   
     
     
         13 . The method of  claim 1 , wherein performing the at least one non-joining and non-cutting finishing treatment of the workpiece comprises at least one of:
 i) removing an oxide layer formed when generating the cutting gap,   ii) removing a burr in the region of the cutting gap,   iii) rounding one or more cutting edges delimiting the cutting gap,   iv) changing a shape of at least one cutting edge delimiting the cutting gap,   v) generating a chamfer along the cutting gap,   vi) heat-treating the workpiece along the cutting gap, or   vii) coating the workpiece along the cutting gap.   
     
     
         14 . The method of  claim 1 , wherein, during performing the at least one non-joining and non-cutting finishing treatment of the workpiece, the partially cut-out workpiece part is not completely cut out of the workpiece and remains firmly connected to the workpiece. 
     
     
         15 . The method of  claim 1 , wherein the processing beam has a first power density for generating the at least one section of the cutting gap and a second power density for performing the at least one non-joining and non-cutting finishing treatment of the workpiece, and wherein the second power density is smaller than the first power density. 
     
     
         16 . The method of  claim 1 , wherein the finishing treatment of the workpiece is performed along one of:
 a finishing line identical to the cutting line, or   a finishing line laterally offset from the cutting line.   
     
     
         17 . A beam processing device comprising:
 a beam head configured to guide a processing beam; and   an electronic control device configured to control beam processing of plate-shaped or tubular workpieces, wherein the electronic control device comprises:
 at least one processor; and 
 one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
 generating at least one section of a cutting gap cutting through a workpiece along a cutting line by a processing beam, wherein the cutting line corresponds to at least part of a contour of a workpiece part to be produced from the workpiece; and 
 performing at least one non-joining and non-cutting finishing treatment of the workpiece with a partially cut-out workpiece part in at least in one section of at least one finishing zone by the processing beam, wherein the finishing zone extends along the cutting line. 
 
   
     
     
         18 . A non-transitory computer readable storage medium having machine-executable instructions stored thereon that, when executed by at least one processor, cause the at least one processor to perform operations for beam processing of a plate-shaped or tubular workpiece, the operations comprising:
 generating at least one section of a cutting gap cutting through the workpiece along a cutting line by a processing beam, wherein the cutting line corresponds to at least part of a contour of a workpiece part to be produced from the workpiece; and   performing at least one non-joining and non-cutting finishing treatment of the workpiece with a partially cut-out workpiece part in at least in one section of at least one finishing zone by the processing beam, wherein the finishing zone extends along the cutting line.
